Also, please make sure you update to the latest firmware version using the PL8's Charge Control Software. The latest version is v3.31 and we did address a bug related to IR readings in this version; in line with what you describe.

I've got the latest version of the firmware and my charger still does this although not as bad. I generally have to just ignore what ever the higher cell reading is, whereever it is. It's always fun watching the 130x batteries with one cell at 29ohm and the other at 55ohm. It does this range of difference on 10 batteries, 5 with 20 cycles and 5 brand new ones. All batteries I have show one cell higher than the rest.

it's the mpa board (set correctly before anyone asks) but I'm using turnigy nanotech batteries with the smal jst connectors. I've made some jst to deans cables so I can charge 5 at a time (only cos I had 5 batteries to start off with) not the standard eflite packs.

Are these the Nanotechs that come with one lead (balance lead which doubles as the 130x connector), or two leads, one with a balance connector and one with a discharge lead? Any chance you have a picture of how the packs are connected to the MPA?

I am seeing this seam phenomenon with 3 PL8 chargers at my field. Latest FW on all of them. 2 of them using the MPA board. 1 of them when switching to the regular cascading balance boards no longer shows the cell 6 IR as high. The another shows it regardless. I have emailed Revolectrix about this and have yet to get a response. We are all charging 6S packs and seeing this.

It's the two lead version. I bought a small adaptor lead that connects to the standard 130 battery lead and has the small two pin connector on the other end. No changes to the 130 so I can use whichever battery I want, although I never use the standard battery now as the nano's are smaller, lighter and have more punch. The higher C versions are better.
